Maybe. it depends on where you patent it. The patent laws are different in different countries. Some countries may not allow natural products to be patented . Was the structure previously known? If so, the best you might get is a "use patent". Is it related to other compounds previously patented which are active the same way? Was the starting organism used for the biological activity?
I'm sorry, there isn't enough information to answer, and this is better left to a patent lawyer.
My understanding is that natural products and their parts in their original form are universal property. But if one manages to modify or synthsize them, they can own the IP and can patent.
It really depends on the country issuing the patent. some countries allow patents of the natural product, others don't. In the USA, that seems to have changed such that it is more difficult to patent a natural product without modification:
Thanks once again Jack Silver , That is helpful. That means one can have more than one patent if they go up to modification. Since modifications (even a small one) can have significant changes to bioactivity and availability.
Ifor bringing this up. will explor e the differences from country to country to see the most convenient one.Once again, you've been so helpful to me. Thank you and thank you Renuka devi J
